High flow injectors, by themselves,
will not increase horsepower. When the
airflow capability of an engine is
increased significantly, additional fuel
must complement the increase in airflow
in order to support more
horsepower. Thus, the proportional
increase of air and fuel together will
increase horsepower.

The factory fuel injection system
operates slightly rich from the factory. Because
of this, certain engine upgrades such as low
restriction air intake/exhaust systems
and/or slight increases in boost
pressure can usually be taken care of by
the factory fuel injection system.

When airflow
increases are substantial and the
factory injectors are unable to keep up,
larger injectors and/or fuel pressure
increases are required. The factory
fuel injection system can usually
accommodate an injector that flows about
15-20% more than stock without
compromising the idle quality or the low
RPM drivability. If the air flow
increase/horsepower target requires an
injector that exceeds a 20% increase
over stock, there are several options.

1.Re-program the factory ECU
specifically for the new larger sized
injectors.
2.Add a piggyback fuel computer
that will allow you to control the
larger injectors.
3.Use a stand alone engine
management system to control the larger
injectors.

If the injectors are significantly
larger (roughly 2 or 3 times larger than
the factory injector size), you will
need to modify the fuel lines/rail to
increase the supply of fuel to the
injectors. Fuel pump upgrades must also
be considered. Stand alone/fully
programmable engine management systems
must be used and more importantly fine
tuned.

Our injectors are suitable for
gasoline as well as leaded race gas.
Alcohol/methanol is extremely corrosive
and should only be used for race only
applications where the user can drain
the alcohol/methanol and “pickle” the
entire fuel system with gasoline at the
end of each day.

Hydrogen, Propane
and Natural Gas injectors are also
available for gaseous applications.

Yes. Injectors over time will
develop deposits inside the injector
preventing it from functioning
properly. Our service will attempt to
solve all of the problems typically
associated with worn injectors. This
includes stopping any drips/leaks,
uniform spray patterns and flow rates to
within 2-3%. This is accomplished with
our ultrasonic cleaning process as well
as a high flow reverse flushing.
O-rings, filters and pintle caps are
replaced. A full, before and after,
calibration report is also provided for
your convenience.

Yes. Our fuel pump dyno can test
many different types of electric fuel
pumps. We can adjust the voltage to
gauge what differences they would have
on flow vs. pressure. We usually start
the test at 35 PSIG and end at about
110PSIG. Many in tank pumps have an
internal bleed off, or pop off valve,
that limits maximum pressure, and
usually operates in the 60 to 70 PSIG
range. This test tells you exactly what
the Horsepower value, or limit of your
pump is.

If you are
increasing the horsepower of your engine
by 30%, - your fuel pump may not be
capable of delivering enough fuel to
support the desired horsepower increase.

Example: If you
have a pump that supports 200 BHP, Natural Aspirated, it will
have to produce at least 100 Lbs. of
fuel Per/Hr at system pressure. (Break
Specific Fuel Consummation of .50 is
considered normal for NA engines.) At
the target Horsepower of 260 BHP the
pump will have to produce at least 130
Lbs. of fuel Per/Hr ,at your system
pressure, to meet your requirements, and
may not be able to provide this
additional fuel.

Our test will tell
you exactly what horsepower your pump
will support from 35 PSIG to maximum
pump PSIG.
